Why nobody will beat Red Bull in Spain

Despite Lewis Hamilton getting to within an ace of Mark Webber's pace in the second free practice session for the Spanish Grand Prix, Mark Hughes explains why he still expects Red Bull to have a clear advantage for the rest of the weekend

'The question is not when he's gonna stop, but who's gonna stop him.'

The quote is from the cult 1970s film Vanishing Point, but it could just as easily be about Sebastian Vettel's 2011 title campaign. While everyone has been very excited by all the overtaking in the first four races, Vettel has effectively led every lap apart from those last few in China. His other races have fallen into an identical pattern: win pole, lead away, get enough of a gap to allow him to respond to his pursuer's pitstop without losing the place, control the gap from there with enough in hand to keep himself out of DRS-trigger reach.
